Remove GET_TARGET() define: this was for compiling iptables for debugging (ie. without -O) on old kernels where ipt_get_target() was defined "extern inline". These days it's "static inline", and only developers build without -O anyway.

Fix up DUMP_ENTRIES a little, but remove calls: it only dumps the table as loaded, not the changed (cached) table, which is misleading.
Fix TC_DELETE_ENTRY: we need to use iptcc_map_target() before comparing, otherwise "-j DROP" (as an example) doesn't work.
